Kitayama Maruta is a general term that includes polished round logs, artiﬁcially and naturally striated logs,
menkawabashira (wood with four planed sides but retaining natural texture) and rafters, with their special
characteristics being a ﬁne wood surface having a velvety and lustrous surfacepolished appearance after thebark is stripped, and having a resistance to drying and cracking.
This reﬁned quality of Kitayama Maruta makes it not only perfect for use in Japanese-style architecture but
it also blends harmoniously with modern-day architecture having various applications as the wood possesses
a reﬁned elegance that lends a feeling of nature to any interior space, bringing humans closer to nature. Thevariegated beauty and crispness of its appearance can readily attract anyone who sees it.
The traditional handicrafts of Kyoto that allow you to sense this 600-year history of Kitayama Maruta havebeen designated as Kyoto-fu Traditional Handicrafts (Kyoto Prefecture) and Kyoto-shi Traditional
HandicraftsManufactured Products (Kyoto City).
Both Kitayama Maruta and Kitayama Sugi have acquired regional organization trademarks such thatthe product quality can be further improved and the brand image of this wonderful wood can be promoted

Kitayama Kitayama
Maruta Sugi
(Japanesecedar logs in the round) that were frequently used for the construction ofandon
tearooms and tea houses that served to support the Cha-no-yu (tea ceremony) culture that was perfectedby Sen-no-Rikyu, giving the wood a history that stretches back some 600 years.
During this time, the persistent efforts and wisdom of our predecessors cultivated the consistent silviculture
and processing techniques we possess today.

Striated Maruta

Kitayama Naturally Striated Maruta
This type has naturally formed knobby texture andwavelike unevenness (striations) in the wood surface
such that it reﬂects various aspects of its growing
conditions such as type, geological features andexposure to the sun. It is mainly used for alcove
posts.

Kitayama Crepe-StriatedMaruta

Kitayama Artificially Striated Maruta

This is one type of naturally
striated Maruta. This type isextremely scarce as although it
has protruding striations ofknobby/wavelike texture, thistype is characterized by its
striations forming long narrowslits.

This natural striation that appears
wavelike in the wood surface is createdartiﬁcially in this product. Two to three
years before being felled, small
chopstick-shaped pieces of wood arewrapped around the trunk to create
striations. This type is generally used foralcove posts.

Polished Kitayama Maruta

Rakuhoku(Wood with four planed sides
but retaining natural texture)
This is fabricated frompolished Maruta using an adzeor similar tools to leave thewood surface of the Maruta
and draw out the beauty of thewood grain.

This is a basic Kitayama Maruta
product. It is characterized by aﬁnely striated wood surface thatis smooth and lustrous, while
having almost no variation fromtrunk-to-tip and being straightwith a rounded shape.

This product provides new
usefulness for Kitayama Maruta as
it has been developed for use as
wood paneling and wallboard.
Possessing the beauty of both thewood surface and wood grain, thisis used in a wide range ofapplications from public facilities tostores and houses.

Honjikomi
Some 60% of the branches are pruned in the winter before felling to suppress
growth and thicken the growth rings (pruning).
In the following summer, the cedar roots are cut and the bark is stripped while
the tree is left standing in the mountain, and then the growing tree is left todry (stripping).
This process creates Maruta that have a lustrous and resistant surface, withan exquisite color tone, and that are resistant to cracking.
